Cross-Species Deworming

by: Craig R. Reinemeyer, DVM, PhD

Question: We have a stable yard with over 50 horses. The horses are on a quarterly deworming program. In the middle of the summer, we deworm the horses for tapeworms. How do the worm infestations of horses and domestic pets, such as dogs and cats, correspond with each other, if at all? If we deworm the horses now, but horse owners' pets are carrying a load of worms, can these animals reinfect the horses again?

Would it be beneficial to run horses and domestic pets (and even their owners) on the same deworming program?
